These tubular ilues do not communicate wi'th the com artments 27 and 28, but are provided for eading the heat or ignited combustion gas through the saine and thus communicate heat to the contents of the hollow disk. The annular lip 35 extending beyond the top face of the disk is intended to prevent any condensed water, collecting on the top of the disk .to drip down through the tubular ilues 34, which otherwise might cause the extinguishing of the flames in the gas burner. Similarly an annular ledge or sweat ring`36 1s provided around the outer riphery of the disk for the purpose of catc ing any condensed water collecting on the top thereof. It will be noted that the dia-meter of the hollow disk is greater than the diameter of the gas burner 23, so that any drippin from the outer periphery of the hollow disk can not injure the gas burner. I

In continuation of the inlet pipe 25 1s furnished a short cylinder 137 extending from the bottom of th'e hollow disk past the to the outlet pipe 30. In this cylinder 1s formed an aperture 38 opening to one side in the lower chamber and along this aperture is shown a radial wall 39 extending from the cylinder 37 to the edge of the hollow disk. Between each of the tubular lues 34 are shown short metallic webs 40 providing a continuous partition with the tubular flues extending from the radial wall 39 around the cylinder 37 leaving, however, an opening between the first and last tubular vents as at 41. By means of this construction the water entering from the inlet pipe 25 is made to pass out through the aperture 38 in the direction indicated by arrows X in Fig. 4 around the cylinder 37 turning outwardly through the opening 41 and running in opposite direction following arrows Y outside of the tuybular iues, linally reaching the passage 42 provided in the horizontal wall 29 entering the upper compartment 27. This compartment 1s similarl constructed but instead of the water fo lowing the inner side of the tubular tlues, as was the case in the lower compartment 28 the water now circulates in the direction indicated by arrows Z in Fig. 5 on the outer-side of the tubular vents and returning through the opening 43, then passing in reverse direction following arrows V around the cylinder 37 and out through an aperture 44 therein into the outlet pipe 30 linally reaching the upper part of the boiler 10.

Referring particularly to Fig. 2 the outlet pipe 30 is entirely surrounded between the top of the casing 13 and the top 33 of the boiler, by a large tlue pipe 45- which opens at its lower end into the casing and terminates with the narrow ledge 46 within the casing. At its upper end, the tlue pipe turned to adjust the flow of air through the' ports21, the gas burner 23 is lit and the water commences to circulate in the heating unit. The cold water enters through pipe 25 into the lower compartment 28 and takes its cii'cuitous path first in one direction and then in the opposite direction and when partly heated rises to the upper coinpartment 27 through the assage 42 and then circulates in opposite direction to what was the case in the lower compartment. It will be evident that the water is heated not only from the as jets striking directly on the bottom of tie hollow disk 26, but also by the heated and ignited combustion gases passing through the tubular flues 34 and also from the combustion gases passing around and above the hollow disk 2G. After having completed its course through the upper compartment 27 the water proceeds upwardly through the outlet pipe 30, where it becomes still more heated from the conibustion gases passing upwardly through the i flue pipe 45 on its helical course along the baffles 47. It will thus be seen that the water is made to absorb heat during its entire course through the heatin unit frein the bottom to the top of the oiler. The water surrounding the casing 13 is also heated through contact with the walls thereof. At no time is there any danger of the heated parts of the casing coming in direct contact with the exterior structure as it is entirely enclosed by water.

It should be noted that the combustion chamber 13 does not necessaril have to be situated as low down in the boi er as is indicated in Fig. 2 of the drawings, but may be placed centrally oi' even higher up therein and the right is reserved for placing the combustion chamber in diferent positions.

Having thus described the invention, what is claimed as new is:

1. A heating unit for boilers comprising a hollow disk having a transverse partition furnishing an upper and a lower compartment therein, a passage in said partition, an inlet port for said lower compartment, an outlet port for said upper compartment, elements in said disk including a radially directed abutment member, and tubes arranged with their axes parallel to the axis of the disk to form an annular wall and providing together with said abutment wall, for the fluid to be heated, a circuitous path through each of said compartments.

2. A heatin unit for boilers comprising a hollow disk aving a transverse partition furnishing an upper and a lower compartment therein, a passage in said partition, an inlet port for said lower compartment, an outlet port for said upper compartment, elements in said hollow disk providing annular circuitous paths through each of said compartments 'for the fluid to be heated, and a casing providing a combustion chamber in which said hollow disk is inserted, said elements including radially directed abutment members and tubes arranged with their axes parallel'to the axis of said hollow disk to form an annular wall, said tubes communicating above and below the disk with said combustion chamber.

3. A heating unit for 4boilers comprising a hollow disk having a transverse partition furnishing an upper and a lower compartment therein, a passage in said partition, an inlet port for said lower compartment, an outlet port for said upper compartment, tubes extending through both of said compartments and arranged as an annular wall and radially directed abutment members toY gether with the tubes providing circuitous paths for the fluid to be heated through each of said compartments, a. casing providing a combustion chamber in which said hollow disk is inserted, a supply pipe leading into said inlet port, and an outlet pipe leading from said outlet port.

1l. A heating unit for boilers comprising a hollow disk having a transverse partition furnishing an upper and a lower compartment therein, a passage in said partition, an

inlet port for said lower compartment, an

outlet port for said upper compartment, tubes extending through both of said compartments and arranged as an annular wall, and radially directed abutment members together with the tube providing circuitous paths for the fluid to be heated through each of said compartments, a casing providing a combustion chamber in which said hollow disk is inserted, a supply pipe leading into said inlet port, and an outlet pipe leading from said outlet port, said outlet pipe opening into the upper end of said boiler.

5. A heating unit for boilers comprising i ving into said inlet port, an outlet pipe leading from said outlet port, said outlet pipe opening into the upper end of said boiler, and a llue pipe surrounding said outlet pipe and having communication with said combustion chamber at one end and the atmosphere at the other end.
